Description
Technical Field
The invention relates to the technical field of construction equipment control, in particular to a method for leveling a hanging basket in high-altitude operation.
Background
The overhead operation hanging basket is taken as an indispensable auxiliary construction facility of a building, the possession of a building site is increased, the overhead operation hanging basket is a construction facility with high risk, accidents of the overhead operation hanging basket are frequent, and the safe use of the overhead operation hanging basket is required to be highly valued.
The lifting operation of the hanging basket is to lift the hanging basket by arranging one lifting mechanism at each of the two ends of the hanging basket, and a safety lock is arranged above and near the lifting mechanisms at the two ends of the hanging basket. The lifting mechanism work steel wire rope passes through the safety lock arm small pulley, the safety steel wire rope passes through the safety lock hole, when the work steel wire rope is in a tensioning state and the inclination angle of the hanging basket is smaller than the locking angle of the safety lock, the work steel wire rope compresses the safety lock arm, the safety lock is in an unlocking state, the safety steel wire rope can freely pass through the safety lock hole, and the hanging basket can freely lift. When the hanging basket moves downwards, the working steel wire rope at the lower end gradually weakens the compression degree of the safety locking arm when the hanging basket tilts downwards, the safety locking arm gradually opens until the tilting angle exceeds the locking angle of the safety lock, the safety steel wire rope in the locking lock hole of the safety lock prevents the safety steel wire rope from passing through the locking hole, the load at the low end of the hanging basket is gradually transferred to the safety steel wire rope from the working steel wire rope, and the low end of the hanging basket is stopped. If the operator does not manually stop the hanging basket from descending at this time, the two lifting mechanisms continue to pay out the steel wire ropes, the working steel wire ropes at the lower end further loosen to disorder the ropes, the high end of the hanging basket continues to descend, the hanging basket gradually becomes a reverse inclination state, and the hanging basket is stopped when the reverse inclination angle is larger than the safety lock rope locking angle, and then the hanging basket is completely stopped in the reverse inclination state. If the operator still stops the hanging basket from descending manually at this time, the working steel wire ropes of the two lifting mechanisms continue to be released, and the hanging basket load is completely born by the safety steel wire ropes at the two ends.
From the above, the present safety lock is used as a safety device for preventing the hanging basket from being inclined to generate safety accidents, and has the following technical defects:
(1) The device can only play a role in limiting the inclination angle under the descending working condition of the hanging basket, and cannot play a role in limiting the inclination angle under the ascending working condition. When the lifting mechanism is lifted, the hanging basket at one end of the lifting mechanism with higher lifting speed is gradually higher than the hanging basket at the other end to enable the hanging basket to incline, when the inclination angle reaches the safety lock rope locking angle, the safety lock at the lower end enables the safety rope to not freely pass through the safety lock hole, the safety steel wire rope is lifted to be loosened, and the weight at the tail end below the safety steel wire rope is lifted continuously along with the hanging basket. At this time, if the operator does not manually stop the lifting of the basket, the lifting of the basket is continued, and the basket is further inclined, so that the lifting direction of the basket is not provided with an inclination protection function.
(2) If the lifting speed difference of the two lifting mechanisms is large, the safety lock rope can be frequently triggered, the damage of the safety steel wire rope and the safety lock can be accelerated, and the service life is shortened.
(3) If the lifting speed difference of the two lifting mechanisms is large, the safety locking rope can be frequently triggered, and the safety locking rope can be frequently stopped for manual leveling, so that the working efficiency is reduced.
(4) The inclination angle limited by the inclination angle protection device completely depends on the braking performance, the structural size and the installation position of the safety lock on the hanging basket, and the inclination prevention angle of the same safety lock can be different when the installation changes or the safety lock with different sizes is installed on the same hanging basket, so that the braking capability of the safety lock is insufficient or the inclination prevention is sequentially failed.
(5) The requirements of hanging basket operators are relatively high, the operator is required to concentrate on not allowing distraction during operation, the horizontal state of the hanging basket needs to be observed at any time, and once the hanging basket is inclined, the hanging basket is stopped for manual leveling before the safety lock rope is not triggered.
During operation, the reasons for inclination in the lifting process of the hanging basket are as follows: (1) The left end lifting mechanism and the right end lifting mechanism are asynchronous, so that the hanging basket is inclined; (2) The left end lifting mechanism and the right end lifting mechanism are not leveled after being independently operated, so that the hanging basket is inclined; (3) manual brake release slipping down causes the basket to tilt; (4) the hanging basket encounters obstruction to incline when ascending and descending; (5) other causes cause the basket to tilt. However, there is a great safety risk for the basket to incline for any reason, and a solution is needed to overcome the above technical problems.

Detailed Description
The invention will be further described with reference to examples and drawings, to which reference is made, but which are not intended to limit the scope of the invention. The present invention will be described in detail below with reference to the accompanying drawings.
The invention provides a method for leveling a hanging basket in high-altitude operation, which comprises the following steps:
SI: the left end lifting mechanism and the right end lifting mechanism lift or descend the hanging basket; the left end lifting mechanism and the right end lifting mechanism are respectively positioned at the left end and the right end of the hanging basket;
s2: when the hanging basket is in a lifting working condition, when the inclination angle reaches a set angle during lifting of the hanging basket, stopping lifting actions of a left end lifting mechanism or a right end lifting mechanism corresponding to the high position of the hanging basket, and waiting for the right end lifting mechanism or the left end lifting mechanism corresponding to the low position of the hanging basket to continue lifting the hanging basket until the hanging basket is leveled to a position within a horizontal or inclination angle range;
S3: after the hanging basket is leveled to a position within a horizontal or inclined angle range in the step S2, the left end lifting mechanism and the right end lifting mechanism lift the hanging basket at the same time;
s4: and in the lifting process of the hanging basket, the step S2 and the step S3 are repeated to realize automatic leveling of the lifting working condition of the hanging basket.
S5: when the hanging basket is in a descending working condition, when the inclination angle reaches a set angle during the descending of the hanging basket, stopping the descending action of the left end lifting mechanism or the right end lifting mechanism corresponding to the lower position of the hanging basket, and waiting for the right end lifting mechanism or the left end lifting mechanism corresponding to the higher position of the hanging basket to continue descending the hanging basket until the hanging basket is leveled to a position within the horizontal or inclination angle range;
S6: after the hanging basket is leveled to a position within a horizontal or inclined angle range in the step S5, the left end lifting mechanism and the right end lifting mechanism simultaneously descend the hanging basket;
S7: and (5) repeating the step (S5) and the step (S6) in the process of lowering the hanging basket so as to realize automatic leveling of the lowering working condition of the hanging basket.
In the step 2, the step 3, the step 5 and the step 6, an automatic leveling control device is adopted to detect the inclination angle of the hanging basket, and the starting and the suspension of the left end lifting mechanism and/or the right end lifting mechanism are automatically controlled so as to realize the automatic leveling of the hanging basket. In the step S2 and the step S5, when the inclination of the hanging basket is leveled, the inclination angle of the hanging basket is not more than 14 degrees, so that the safety lock is ensured not to trigger the locking rope before triggering the leveling.
According to the method for leveling the hanging basket in the high-position operation, when the inclination exceeds the standard during the lifting of the hanging basket, the lifting mechanism at the high position is stopped, and when the lifting mechanism at the low position is continuously lifted to be close to the horizontal, the lifting mechanisms at the left end and the right end are lifted simultaneously; when the hanging basket descends, the hanging basket tilts beyond the standard, the lifting mechanism at the low position stops, and the lifting mechanism at the left end and the right end simultaneously descends after the lifting mechanism at the high position continues to descend to the approximate level. As long as the inclination angle exceeds the standard, no matter any operation (linkage, left single operation and right single operation), the high-position lifting mechanism cannot lift again, the low-position lifting mechanism cannot descend, namely the inclination angle cannot be worsened any more, and the operation can only be carried out towards the direction of reducing the inclination angle. The high-altitude operation hanging basket leveling method can automatically level hanging baskets in any operation and running state, ensure that the hanging baskets continuously and safely run in a set levelness range, prolong the service lives of the safety steel wire ropes and the safety locks, and improve the working efficiency without stopping the leveling operation; meanwhile, the successive failure of the braking anti-tilting capability of the safety lock is avoided, and the tilting accident of the overhead operation hanging basket can be effectively restrained.
Referring to fig. 1 to 8, the automatic leveling control device includes a case 1, a weight 2 rotatably mounted to the case 1, and a limit switch 3 mounted to the case 1 and located below the weight 2; the limit switch 3 comprises a right-tilting limit switch K1, a left-tilting limit switch K2 and a reset switch K3;
The bottom of the heavy hammer 2 is provided with a K1 trigger boss 10, a K2 trigger boss 20 and a K3 trigger groove 30; when the hanging basket is in a horizontal state, the right-tilting limit switch K1 is positioned on the right side of the K1 trigger boss 10, the left-tilting limit switch K2 is positioned on the left side of the K2 trigger boss 20, and the reset switch K3 is positioned in the K3 trigger groove 30.
In this embodiment, as shown in fig. 8, the limit switch 3 is a combined limit switch, and three limit switches of a right-leaning limit switch K1, a left-leaning limit switch K2 and a reset switch K3 are combined to obtain a triple automatic reset combined switch. The right-leaning limit switch K1, the left-leaning limit switch K2 and the reset switch K3 belong to the existing limit switches, so that the description is omitted.
In this embodiment, the right-tilting limit switch K1 is used to control the right-tilting angle of the basket; the left-tilting limit switch K2 is used for controlling the left-tilting angle of the hanging basket, and the reset switch K3 is used for detecting that the hanging basket is leveled in place. The right-leaning limit switch K1 and the left-leaning limit switch K2 are closed when working normally, are opened when the inclination angle exceeds the standard, and the reset switch K3 is closed only when the hanging basket is close to the horizontal state.
When the hanging basket is in the ascending working condition in practical application, no matter what cause, if the hanging basket is inclined rightwards, namely, the hanging basket is high leftwards and low rightwards, the box body 1 drives the right-tilting limit switch K1, the left-tilting limit switch K2 and the reset switch K3 to rotate clockwise around the heavy hammer 2, the right-tilting limit switch K1 is gradually close to the K1 triggering boss 10 until triggering, the right-tilting limit switch K1 is disconnected, the left-end lifting mechanism is powered off to stop rotating, and the left end of the hanging basket is stopped to be lifted. At the moment, the inclination angle of the hanging basket is the triggering angle of the automatic leveling control device, the angle can be adjusted steplessly according to the requirement, and the angle is far smaller than the locking rope angle of the safety lock, namely the safety lock does not trigger the locking rope before the automatic leveling control device triggers, and at the moment, the automatic leveling control device does not need to stop leveling. The right lifting mechanism can continuously lift and slowly catch up with the left end to automatically level the hanging basket. In the leveling process, the box body 1 drives the right-tilting limit switch K1, the left-tilting limit switch K2 and the reset switch K3 to rotate anticlockwise around the heavy hammer 2 until the right-tilting limit switch K1 is reset and turned on after the hanging basket approaches to a horizontal state, the reset switch K3 is reset and turned on, the left lifting mechanism starts to lift, then starts to lift synchronously left and right, and the leveling is finished. And starting the leveling control again until the inclination angle is increased to the trigger angle due to the increase of the height difference at the two ends of the hanging basket. The automatic leveling control device automatically controls the inclination angle of the hanging basket to continuously run within a set range, and does not need to stop machine for manual leveling.
If the hanging basket is inclined leftwards, namely left and right are low, the automatic leveling control device controls the power-on and power-off of the right lifting mechanism to automatically level through the left tilt switch contact K2 and the reset switch K3. When the hanging basket is in the descending working condition, the working principle is the same as that of the hanging basket in the ascending working condition, so that the description is omitted.
In the high-altitude operation hanging basket leveling method, an automatic leveling control device is adopted to automatically level the hanging basket in any operation and running state, so that the hanging basket can be ensured to run continuously and safely in a set levelness range, the service lives of a safety steel wire rope and a safety lock are prolonged, leveling operation is carried out without stopping, and the working efficiency is improved; meanwhile, the successive failure of the braking anti-tilting capability of the safety lock is avoided, and the tilting accident of the overhead operation hanging basket can be effectively restrained.
